A rare photo taken by ISS flight engineer, Terry Virts, during his third and final spacewalk has captured the real grandeur of the International Space Station, with station commander Barry “Butch” Wilmore barely visible in the awesome shot.

Spacewalkers Virts and Wilmore completed their third spacewalk in
eight days on Sunday, to rig new docking spots. The astronauts
celebrated 100 days in space with a "Day 100 badge." They've only
got two and a half months to go and time is flying "way too
fast," Virts complained on Twitter.

The challenge was to prepare berths for spaceships developed by
Boeing and SpaceX. They had to install over 122 meters of cables,
a pair of antennas and reflectors the new spaceships will
navigate toward and dock with the station, a $100-billion
laboratory about 418 kilometers above Earth.

The astronauts were expected to spend up to seven hours on their
mission. Instead, the savvy astronauts were back inside the space
station in 5 and a half hours. Their three outings spanned 19
hours, over which time they installed over 240 meters of cable
and several antennas.

After the spacewalk, Virts said that a small amount of water had
seeped into his helmet. According to mission commentator Daniel
Huot, it was "no issue to crew safety."

In 2013, death was just a breath away for Italian astronaut Luca
Parmitano who nearly drowned when water began leaking into his
helmet. NASA immediately aborted the mission and suspended
spacewalks while engineers tackled the problem. NASA said the
incident with the suit Virts was wearing is unrelated.

In an effort to stop being reliant on the Russian Space Agency,
NASA has hired Boeing and SpaceX to develop spacecraft capable of
transporting astronauts to the space station. The two contracts
are worth nearly $7 billion. However, NASA will buy Russian Soyuz
seats for its astronauts through 2018 in case the two companies
miss their promised 2017 launch deadline.

The first man to walk in space was Soviet cosmonaut Alexei
Leonov, on March 18, 1965. He beat America's first spacewalker,
Edward White II, by just over two months. Leonov’s pioneering
walk nearly cost him his life. After 12 minutes on the outside of
the spacecraft, as he received the order to return, the cosmonaut
realized something was wrong. Lack of atmospheric pressure had
caused his spacesuit to inflate like a balloon, so he couldn't
get back inside the capsule. Leonov acted fast and siphoned off
fifty percent of the air in his spacesuit, although this risked
starving his own body of oxygen. The cosmonaut was supposed to
re-enter the craft feet first, but he "did it his way" -
head-first. He then had to turn himself around in a tiny tight
space to pull in the "umbilical cord," which had kept him from
falling off into space.
